Right clicking into input bar instantly freezes Vivaldi for several seconds

Hi, like the title suggests, I have a really annoying problem with Vivaldi. When I right click into any bar that I can write in e.g. the search bar of Reddit or of this forum or even the address bar of the browser, the browser will freeze immediately for several seconds and crash. Basically I can't use the right click options on any input bar. I use Vivaldi 1.3.551.38 (Stable channel) (32-bit) on Win 7 Pro on my Laptop and Win 10 Pro on my PC. Any suggestions?
